Soil Infiltration Variability Across Diverse Soil Reference Groups, Textures, and Land-Use Types
Soil infiltration—the process through which water enters and percolates through the soil profile—varies widely across soil reference groups, textures, and land-use types. This variability is shaped by inherent soil characteristics and external ecosystem pressures. Coarse-textured soils such as sandy soils generally exhibit higher infiltration rates due to larger pore spaces, while fine-textured clay soils tend to have slower infiltration because of compacted micropores and higher water-holding capacity. Soil reference groups like Fluvisols, Andosols, or Cambisols often display strong infiltration potential owing to their porous structure and organic matter content, whereas Vertisols and Luvisols typically show restricted infiltration due to swelling clays and dense subsoils. Land-use practices further influence infiltration behaviour: natural forests and well-managed agroforestry systems enhance infiltration through increased litter cover, root activity, and soil biological proces...
